So I have picked a lovely 2004 Wrx and keep on having to change out the halogen driving bulbs. In the 18 months I have owned this lovely little racer, I have had to replace the burntout bulbs on either side at least 6 separate times. I have used factory replacement, silverstar and basic halogen.They don't seem to last more than 3-4 months before one side goes. Any more technical savy folks out there with a similar problem and better yet perhaps a solution for me?? I have changed these myself and via the dealership.
